对话框与自定义视图背景

解决:见下面的答案

我正在对Dialog进行子类化以创建具有自定义背景的对话框。我已经在Dialog中添加了一个子类View,它正确地绘制了位图背景和布局。但按钮不会响应任何触摸事件。

我怀疑必须在Dialog类中加载LinearLayout,但我想我必须在视图类中加载它以在位图之上绘制。

我是Android开发人员的新手,所以我为这个问题道歉。这就是我在做的事情:

public class CustomDialog extends Dialog {

private static final String TAG = "CustomDialog";
private static int layoutWidth = 640;
private static int layoutHeight = 400;

public CustomDialog(Context context) {

    super(context, android.R.style.Theme_Translucent_NoTitleBar);

    requestWindowFeature(Window.FEATURE_NO_TITLE);

    LayoutParams params = getWindow().getAttributes(); 
    params.width = LayoutParams.FILL_PARENT;
    getWindow().setAttributes((android.view.WindowManager.LayoutParams) params);

//      setContentView(R.layout.layout_dialog); // This works fine, the buttons work
    setContentView(new NewLayoutDialogView(context));
}

public static class NewLayoutDialogView extends View {

    private Drawable bg;
    public LinearLayout layout;
    private OnColorChangedListener mListener;

    public interface OnBrushChangedListener {
        void brushChanged(float radius);
    }

    NewLayoutDialogView(Context context) {  

        super(context);

        InputStream stream = getResources().openRawResource(R.drawable.dialog_bg);
        bg = NinePatchDrawable.createFromStream(stream, null);

        layout = (LinearLayout) LinearLayout.inflate(context, R.layout.layout_dialog, null);

        Button ok = (Button) layout.findViewById(R.id.ok_button);

        layout.setWillNotDraw(false);

        layout.setVisibility(View.VISIBLE);
        setVisibility(View.VISIBLE);

        layout.measure(layoutWidth, layoutHeight);
        layout.layout(0, 0, layoutWidth, layoutHeight);
    }

    @Override 
    protected void onDraw(Canvas canvas){

        if (bg != null) {
          bg.setBounds(10, 0, canvas.getWidth(), canvas.getHeight());
          bg.draw(canvas);
        }

        layout.draw(canvas);
    }
 }
}

编辑:这就是我设置监听器的方式。我必须在使用View子类时禁用此代码,如图所示。但是按钮仍然应该显示没有监听器的点击状态,而不是。

        Dialog dialog = new ChangeLayoutDialog(getActivity());      

        Button cancel = (Button) dialog.findViewById(R.id.cancel_button);
        cancel.setTypeface(font);
        cancel.setOnClickListener(new View.OnClickListener() {
          public void onClick(View v) {
              dialog.dismiss();
             }
          });

        Button ok = (Button) dialog.findViewById(R.id.ok_button);
        ok.setTypeface(font);
        ok.setOnClickListener(new View.OnClickListener() {
          public void onClick(View v) {
              dialog.dismiss();
              setCellLayout(layoutFile);
             }
          });

答案 0 :(得分:1)

不是添加子视图类和绘制背景,我需要做的就是添加:

getWindow().setBackgroundDrawableResource(R.drawable.dialog_bg);

我想我只是太努力了!
